Relating to or having the quality of resembling ethene, describing compounds with ethene-like structural or chemical characteristics.
From ethenoid + -al (adjective suffix). This is the adjectival form of ethenoid, adding an extra suffix layer to create a more formal or technical descriptor.
Double suffixes like -oid + -al are common in scientific language—they create increasingly specific descriptions, so 'ethenoidal' is more technically nuanced than just calling something 'ethene-like.'
